Vulnerability Title
Termix's TOTP two-factor authentication can be disabled or bypassed using only the account password
Source: CVE Program / CVE List V5
Vulnerability Description
Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. The `POST /users/totp/disable` and `POST /users/totp/backup-codes` endpoints in Termix prior to version 2.3.2 accept the account password as a sole authentication factor for MFA-critical operations. An attacker who obtains a user's password (phishing, credential stuffing, the passwordHash leak in GHSA-xxxx) can disable TOTP entirely or regenerate backup codes, without ever possessing the TOTP device or knowing a valid TOTP code. This renders two-factor authentication ineffective. Version 2.3.2 patches the issue.
